A proposed solution to this is to check if they were specified in extra_headers and use those, instead of creating default ones.

i.e.

{{{
if not 'Date' in self.extra_headers: 
    msg['Date'] = formatdate()
if not 'Message-ID' in self.extra_headers:
    msg['Message-ID'] = make_msgid()
}}}"		closed	Core (Mail)	1.0		fixed		densetsu.no.ero.sennin@… nreilly@…	Unreviewed	0	0	0	0	0	0
